Their setup was MPC-HC, FFDShow, and LAVSplitter. I'd say that setup is better, but it sounds like the setup you found is working good, may as well keep it that way . But FWIW the guy he was replying to said he got better performance with it vs. MPC-HC and CCCP.

One last note, there's and option in AMD's Vision Center (CCC) to enable hardware acceleration for internet video. Click on the video tab on the left hand side and then video settings. Make sure under "video playback" that the slider is on green for "apply current video quality settings to internet video".
